Title: Electric coffee machine with a centrifugal filter
Inventor: LEUSCHNER UDO
IPC: A47J31/22
Filed: 1982-11-10
Abstract: The invention relates to an electric coffee machine, with a centrifugal filter which is driven by an electric drive motor arranged centrally under it, and with a collecting pan for the sprayed-off coffee, from which pan the coffee is dispensed into coffee cups which can be arranged to the side of the motor. A coffee machine of this type which has a compact design and which is easy to operate is to be provided. 
<??>To achieve this object, it is proposed to arrange the positions for the coffee cups at least partially around the drive motor. Since the motor usually has a smaller diameter than the collecting pan for the coffee sprayed off from the centrifugal filter, in this region the housing can have a contraction or indentations, and the coffee cups can project directly under the collecting pan, with the result that short and easily cleanable outflow channels on the collecting pan can be achieved.

Title: Pneumatic winter tyre for a vehicle
Inventor: TRABANDT HAGEN
IPC: B60C11/11
Filed: 1982-12-02
Abstract: The invention is based on tyres of this kind in which the tread is composed of four circumferential rows with essentially rectangular blocks extending transversely with respect to the circumferential direction of the tyre. So that these tyres are given improved grip not only when the undersurface is soft but also when the undersurface is solid, covered in snow or ice, the blocks located between the laterally outermost circumferential rows are provided on their edges extending transversely with respect to the circumferential direction of the tyre with fine indents which are intended to form angles of approximately 15 to 30 DEG  with respect to the circumferential direction of the tyre. The edge parts, of the blocks, equipped with these fine indents are zigzag-shaped or wave-shaped, the fine indents starting from the troughs of the waves of these edge parts.
Patent DE-3246776-A1 (DE)
Title: Process and device for the finish-machining of hardened gearwheels
Inventor: EHRLICH WILLIBALD
IPC: B23H9/00
Filed: 1982-12-17
Abstract: The invention relates to a process and device for the finish-machining of hardened gearwheels by means of a cutting, shaping tool rolling in the toothing to be machined. To be precise, the electrical discharge method known per se is used between shaping tool and gearwheel. The shaping tool may be a cylindrical or an enveloping worm, it may be a counter-gearwheel, corresponding to the shape of the gearwheel to be machined, or else it may be a toothed rack. The invention makes it possible not only to finish-machine, even in a hard state, such gearwheels which previously could not have been finish-ground, or only with unacceptably great expenditure, but also, by virtue of the electrical discharge method, to produce great accuracies and, in particular, surfaces which are diffuse in their microstructure, which are particularly advantageous with regard to their emergency-running characteristics and with regard to the premature development of a hydrodynamic lubricating film between the tooth flanks. Thus, gearwheels finish-machined in such a way can be expected to provide not only higher finishing accuracy, but also greater efficiency, lesser wear and greater pitting tolerance.

Title: Stock slide valve, in particular for massecuite
Inventor: MAINKA HELMUT
IPC: B04B3/00
Filed: 1983-03-08
Abstract: A stock slide valve designed to control the flow of massecuite has an orifice plate (20) which is arranged in a through opening (22) of the inlet pipe of a centrifuge and the aperture (21) of which is smaller than the through opening (22), the aperture (21) interacting with a sliding plate (23) which can be displaced between an end position in which it closes the aperture (21) and an end position in which it opens the latter. The aperture (21) is arranged in such a way within the through opening (22) that the centre of gravity of its area is offset relative to the centre of gravity of the area of the through opening (22) in the direction (32) of opening of the sliding plate (23). In the main operating position of the stock slide valve, which corresponds to the rated flow rate of the latter, the aperture (21) is opened to an extent such that the centres of gravity of the areas of the free cross-sectional area (25) and the through opening (22) approximately coincide. In this way, the flow of stock to be controlled is made to flow in the centre. <IMAGE>

Title: Method for the production of a built-up camshaft
Inventor: STOCKBRIDGE JOHN NORMAN
IPC: F16H53/02
Filed: 1983-12-16
Abstract: For a built-up camshaft, individual elements which have bearings or cams are produced as individual parts, these elements having mutually parallel end faces and expediently being of hollow design. They are essentially machined to their final dimensions, except on the bearing surfaces and the cam surfaces, where an oversize is provided, which is then machined to the final dimensions once the camshaft has been assembled. The individual elements are connected one after the other in a predetermined sequence and in a predetermined angular position relative to one another with a common longitudinal axis by friction welding. It is thereby possible to produce a lighter-weight camshaft and difficulties associated with other welding methods arising from deformations due to the heat of welding are largely eliminated. <IMAGE>
